Did they part in the Korean War at all or did they arrive too late?
If they did take part which squadrons did they fly with?
What do you need to build a Canberra from the Korean War and
Vietnam in 1/48?

Hi Jan,
Canberras weren't deployed to the Korean theatre by any airforce.
Australian Canberras served during the Vietnam war.
The Australian, Government Aircraft Factory (GAF) built 48 for the RAAF, broadly similar to the British B.2 but with a modified leading edge and increased fuel capacity.
The American, Martin Canberra's were the B-57B and also served in Vietnam.
The soon to be released Airfix kit has options for both of these aircraft in 1/48.
Collect-Aire do a B-57B.
Classic Airframes do the Australian B2 export version.
